Greece travel guide

Greece combines the monuments of classical antiquity with thousands of islands, clear seas and a relaxed food culture built around tavernas and long evenings. It suits island-hoppers, beach lovers, walkers and anyone drawn to ancient history, and it rewards those who travel outside the July and August peak.

Highlights

Athens and the Acropolis

The Parthenon and the other temples on the Acropolis rise above a busy modern capital. Pair them with the Acropolis Museum, the Ancient Agora, the National Archaeological Museum and evenings in the Plaka and Psyrri districts.

Santorini

A volcanic island built around a flooded caldera, with white villages such as Oia and Fira clinging to the cliff edge, black and red sand beaches and the excavated Bronze Age town of Akrotiri. Visit outside midsummer if you can.

Crete

Greece's largest island has the Minoan palace of Knossos, the Venetian harbours of Chania and Rethymno, mountain villages and the Samaria Gorge, one of Europe's best-known hikes, as well as some of the country's best food.

Meteora

Monasteries perched on top of giant sandstone pillars in central Greece. Several are open to visitors, reached by steps cut into the rock; modest dress is required.

Delphi

The sanctuary of Apollo, home of the ancient oracle, sits on the slopes of Mount Parnassus with views down to the Gulf of Corinth. An excellent museum holds the finds.

The Peloponnese

A peninsula of ancient sites and quiet coast: Olympia, birthplace of the Olympic Games; the theatre at Epidaurus; Mycenae; the Venetian town of Nafplio; and the fortified rock of Monemvasia.

The Ionian Islands

On the west coast, Corfu, Kefalonia, Lefkada and Zakynthos are greener than the Aegean islands, with Venetian-influenced towns and coves of turquoise water.

Thessaloniki

Greece's second city has Roman and Byzantine monuments, the White Tower on the seafront, a strong café culture and a reputation for some of the best food in the country.

Interesting facts about Greece

  • Greece has around 6,000 islands and islets, but only about 200 or so are inhabited.
  • No point in Greece is more than about 140 kilometres from the sea.
  • Mount Olympus, legendary home of the gods, is the country's highest mountain at about 2,918 metres.
  • Greek has been written for around 3,000 years, and many English words, from 'democracy' to 'telephone', come from it.
  • Nodding the head upwards with a click of the tongue means 'no' in Greece, which can confuse first-time visitors.

Best time to visit

May, June, September and early October are the most pleasant months: warm seas, long days and fewer crowds than midsummer. July and August are hot, ferries and islands are at their busiest, and the strong meltemi wind can make Aegean crossings choppy. Heatwaves sometimes close archaeological sites in the middle of the day. Winter is mild on the coast but many island hotels and tavernas close from November to April, while Athens, Thessaloniki and the mainland mountains stay open all year.

Getting around

Ferries are the backbone of island travel, from slow conventional boats to faster catamarans, and timetables vary by season, so book ahead in summer. Domestic flights link Athens with Crete, Rhodes, Santorini and many other islands. On the mainland, long-distance KTEL buses cover most towns, and trains run between Athens and Thessaloniki. Athens has a metro, trams and buses; the metro runs to the airport and the port of Piraeus. Renting a car or scooter is the easiest way to explore larger islands, but roads can be narrow and winding.

Staying connected in Greece

4G coverage is good in Athens, Thessaloniki, the main towns and on the popular islands, and 5G is available in larger cities. Signal can be weak or absent in mountain areas, on remote islands and on some stretches of sea during ferry crossings. Wi-Fi is common in hotels, cafés and beach bars, and many ferries offer it, though often slowly. A working phone is useful for checking ferry changes. Install an eSIM before you fly and switch it on when you land.

Common questions

Which Greek islands are best for a first visit?

It depends on what you want. Santorini and Mykonos are the most famous but busiest. Naxos and Paros are good all-rounders with beaches and villages, Crete has enough for a whole trip, and the Ionian islands are greener and suit families.

Can I use my phone and mobile data in Greece?

Yes. Coverage is good in towns and on most popular islands, though it can drop at sea and in remote areas. A travel eSIM gives you local data from arrival without changing your physical SIM.

Is Greece open in winter?

Athens, Thessaloniki, Crete's cities and the mainland are open all year, and archaeological sites are quieter in winter. Many smaller islands largely shut down outside the season, with fewer ferries.

Can I drink the tap water?

Tap water is generally safe in Athens and most mainland towns. On some islands it is desalinated or hard and many people drink bottled water, so ask where you stay.
